' ALARM DEVICE.

To all whom it may concern:

Be it known that I, Gnome J. LYNCH, a citizen of the United States, anda resident of New York, county and State of New York, have invented a.certain new, and useful Improvement in Alarm Devices, of which thefollowing is a full, clear, and exact specification.

This invention relates more particularly to a type of alarms adapted tobe used in the signaling device disclosed in my pending application fora patent, serially numbered 193,315, filed September 26, 1917, and

has for its ob ect primarily to provide ade vice wherein a lamp and abell are combined for utilization on an automobile and other vehicle sothat by closing a normally open electric circuit the lamp will belighted and the bell rung synchronously for sounding an alarm ofimpending danger in emergency. The invention consists essentially of acasing with an exposure opening which may be opened and closed by aglass door, and in the casing is a partition dividing the interior ofthe casing into two chambers. The partition is provided with a supportfor removably holding an electric lamp, while on the casing is a bell,and both the lamp and the bell are interposed in a normally openelectric circuit for being closed to light .the lamp and ring the bellsynchronously so that the warning of impending dangenmay be heard aswell as observed.

' Another object of the invention is to pro vide in the casingelectrically operative means to cause a simultaneous ringing of the belland lighting of the lamp; and to provide an alarm device of a simple andeffi'cient construction which may be made in various shapes and sizes.

A practical embodiment of the invention is represented in theaccompanying drawing forming a part of this specification in whichsimilar characters of reference indi cate corresponding parts in all theviews, the said invention being more fully described hereinafter, andwill. then be pointed out in the claims at the end of the description.In the drawing, Figure 1 is a front elevation, partly broken away andpartly in section, of one form of alarm device embodying my invention,and

Fig. 2 is a detail vertical longitudinal section taken through the alarmdevice.

Application filed November 13, 1917. Serial No. 201,832.

The lamp 10 has a casing 12 which is'preferably of substantially acone-shape, and hinged or otherwise attached to the casing is a. glassdoor-13 of a red, green, white or other color for allowing the open endor entrance. to the casing to be opened and closed. Arrangedtransversely of the interior of the casing 12 at the door 13 is aremovable or fixed partition 1 1 of preferably a parabolic shapedisposed so that its concavity is in opposed relation to the glass door.This partition is of a curvature whereby its central part is positionedapproximately midway of the interior of the casing, and the surface ofthe partition 0pposed to the door may be silvered, or polished, orcovered with mirrored glass to provide a reflector 15 for reflectingrays of light through the glass door. By providing the partition in thisfashion the interior of the casing 12 is divided into a front chamber 16and, a rear chamber 17, and through the center of the partition as wellas through that one of its ends protrudes into the front chamber 16 ofthe casing besides protruding exteriorly of the casing. The end portionof this tubular socket member disposed through the opening 18 of thecasing is exteriorly threaded, and on this threaded part interiorly ofthe casing may be a nut 22, while on the threaded part exteriorly of thecasing may be a second threaded nut 23. By screwing these nutsaccordingly they will be moved into engagement with the wall of thecasing, and in turn the socket member will be held against accidentalmovement in the casing. In the end of the socket member 21 whichprotrudes into the front chamber 16 of the casing is mounted an electriclamp -24 of any well known or preferred type for being lighted so thatits rays of light will be reflected by the reflector 15 through theglass door 13 of the casing for being observed by a person to signalimpendin danger.

The nell 11 is preferably formed of a sound producing metallic shell, orhood 25 of somewhat the shape of an inverted cone, and the apex of thiscone-shaped shell is mounted, at 26, on the upper end of a tubular post27. The lower end of the tubular post 27 is exterior-1y threaded, andthis threaded end of the post is screwed into the threaded opening ofthe casing 12 of the lamp. On the threaded end of the post in the rearchamber of the casing is screwed a nut 28, while on the threaded part ofthe post exteriorly of the casing of the lamp is another nut 29, and byscrewing these nuts acccordingly they will be moved into clampingengagement with thecasing of the lamp so that the post with the shell 25will be tlghtly held to the lamp. Through the tubular post 27 inproximity to the open end of the metallic shell 25 of the bell is anopening 30 through which is movably disposed a hammer 31 for ringing thebell. This hammer is preferably in the form of a rod disposed rightangularly with respect to the post, and on the free end of the rod is ametallic ball in closely spaced relation to the metallic shell so thatwhen the rod is vibrated crosswise in the shell the ball will contactintermittently with the shell for ringing the bell. The hammer 31 isprovided on the upper end of an-armature 34 which is in the form of ametallic bar movably disposed in the tubular post, and this armature orbar is of a length to extend through the open end of the post for somedistance into the rear chamber 17 of the lamp casing 12.

Part of the armature is in spaced proximity to the cores of two magnets35 and 36 provided interiorly of the chamber 17 of the casing of thelamp. The magnets 35 and 36 may be of any well known or preferred typesadapted to be energized for vibrating the armature 34 through the mediumof a normally open electric circuit, as 37, which when closed will causethe lamp 24 to be lighted synchronously with the ringing of the bell, aswill be hereinafter more fully explained. The lower end of the armature34 is pivoted, at 38, to a bracket 39 which also supports the magnets 35and 36, and this bracket is held stationary in the rear chamber of thecasing by being bolted or otherwise secured, as at 40 and 41, to thewall of the casing of the lamp. The mag nets 35 and 36 are coupledtogether by a wire, as at 43, and extending from the pivoted end 38 ofthe armature 34 is a spring finger 44 arranged so that its free end isadapted to contact with the bracket 39 for serving to cause the armatureto be swung from the cores of the magnets. Also to the pivoted end ofthe armature 34 is secured one end of another spring finger 45 which isdisposed upwardly in spaced parallel relation to the face of thearmature which is opposite to the magnets. The free end of the springfinger 45 is in movable contact with a set screw 46 rotatably held inpart of the bracket 39 so that by adjusting this screw accordingly thearmature will be properly positioned for being actuated when the magnets35 and 36 are energized by closing the electric circuit 37.

The circuit 37 may be similarly provided as well as being opened andclosed in a like manner to the electric circuit disclosed in my pendingapplication for a patent for signaling device for vehicles, Sr. No.193,315, filed September 26, 1917, and which includes two wires 47 and48 leading from a battery, not shown, or other suitable source ofelectricity supply to the poles of the lamp 24 through the tubularsocket 21. To part of the wire 47 interiorly of the socket of the lampis connected a wire 49 which passes through an opening 50 in the socketto armature 34, and from the set screw 46 is a wire 51 leading to themagnet 36. From part of the wire 48 interiorly of the tubular socket 21is a wire 52 which leads to the magnet 35 so that when the circuit isclosed the current will pass over the wires 47 and 48 to light the lamp24. With the closing of the circuit, the current will pass over wire 52to the magnet 35, over wire 43 to the magnet 36 and over wire 51 to theset screw 46. From the second terminal of the battery the current willpass over wire 49 to the armature 34 so that, with the energizing of themagnets, said armature will be attracted to the poles of the magnets,and the spring 44 will then cause the armature to be released to causethe spring 45 to be recontacted with the set screw 46, so that the bellwill be rung with each closing of the circuit.

In the foregoing description, I have embodied the preferred form of myinvention, but I do not wish to be understood as limiting myselfthereto, as I am aware that modifications may be made therein withoutdeparting from the principle, or sacrificing any of the advantages ofthis invention; therefore I reserve to myself the right to make suchchanges as fairly fall within the scope thereof.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. The combination with a lamp having a casing dividedinto a front light chamber and a rear chamber by means of a concavereflector, of a sound producing shell mountei upon the exterior of thelamp casing and spaced therefrom by means of a tubular post, actuatingmeans mounted in said rear chamber of the lamp casing and including anactuated member extending through said tubular post with its free end ata point adjacent said shell outside of the lamp casing, and a hammer onthefree end of said actuated member.
